Bad service

Certain things just need common sense from whoever is managing a big brand like nedbank. I went to nedbank Vanderbilpark, I get given a ticket number and waited for my turn to get called. Although deep down I was dissatisfied that only two tellers were there to help us I nevertheless waited patiently for my number to get called. After sitting down for 30 min or so my number was called. Upon my arrival at the counter I get told that the network is offline I can’t be helped with card replacement. Look I understand that this things happens but at least People should have been informed about the network issue prior, than sitting the whole 30 min and then being told you can’t be helped. I think management of Nedbank Vanderbijlpark could have done better!
